Controller Reprogramming

Our script fetches results from Google, Yahoo, Bing, Amazon, eBay (API-s). The fetching works only with Google, but does not work correctly. The search controller isn't working with these API-s. It only works with Google and eBay API. But even with Google it has some bugs. We want to reprogram it from the start so it could work with all API-s. The same issue is also in the mobile controller(in the mobile controller the Google API works correctly).
